My invention relates'ito etchingv or fmachines, and'more particularly to machine of this type whereinthe work plate or sheet and the pattern will. both he within the line of vision of the operator 'so as to permit the condition of the work to be noted as it progresses, and thus avoid the' necessity for the repeated;interruption of the operator in the actuation of the tracing stylus in order to inspect the. plate.

the work support being upon a higher planetha'n the pattern table so that inspection of the 7 work required the ',operator to stand,

although the tracing stylus might he used while the operator was seated. v Since frequent, nspectlo'n -1s' necessary,

the above conditions had the efi'ectof reducing the capacity output of a machine and of making its operation awkward for the operator in the event that it were attempted to actuate the tracingf .stylus with relation to the pattern while in z t position to, atLthe same time, observethe working conditions 7 of the work point. 3

WVith the above conditionsin mind, have devised a'machine wherein the work, supporting table" has the nature Qof an easel by means of which the work plate or sheet -may, be supported upon a plane at right ;angles' to that slightly above same so that the operator may move the stylus in accordance with theof .the pattern tahle and depressed lines of a pattern to impart the desired corresponding jmovementl to the Work polnt arm, and'atthesame time closely follow the movements otthe point carried;

imparting vertical movement to the vork p oint; carrying rm" may also be e ployed v to utilize the operative effect ofthe v transmitter arm tocau'se-anfincreased orreduced by said arm. and constantly observe the working conditions at the plate. This ar rangement otjthe work supportnotonlyre- 'quires movement of theworlg point arm toward and from the support to, ensure the 1 engagement or disengagement of' the point a atwith the plate, but requires an; actuating zontal lines; looth' movements of necessity being suchas not to interferewith the-en:

gaging relation of the work point with the plate.

1 It is desirable to 11m 211 ithefwofkifig mechanisms of the machine rearward-1y got the easel-'like work support soas to-afi'ord a "clear held of visionforwardly of said support, which condition necessitates a particular' construction of stylus arm' and transmitter'farm for ensuring the desired universal' movement of ,thei'latter while affording sufficient rigidity inthe actuating gme'ans to secure the desired accuracy -in"the, movement of the 'carriage'flreceiving'its motion from said transmitterar'm." "I al so'provide V "supplemental means for preventing that I minute distortion iiithe' reproduction due to r slight skewing'motion'of the actuating earriage, although this mechanism is not essentialito the inventiong asthe' distortion is not length of the vertical lines are controlled carriage, which mechanism isth'at heretoadjuistment. to} permit it to be so set as'to This a adj ustahility ofthe mechanis'm'jjfor great and may he corrected'by other known In a machine emhodying my invention, the .const ructi'on issuch' that theopei'ative le- .vierag 'e of the" transmitter. arm 'maybe'v'a ried to control whatgmay termed'thel nor- T jmal scale? ofthe reproduction; althoughlthe by a me clianism carried hy the actuating r fore referred to as convertinglthe fore and V aft movement of the. carriage upon a horizontal, plane; into a vert icahmovement of the Work pointcarrying-farm. ltjis-appar ent that thisfmecha'nismj must be "capable'of 1 length of the. vertical linejs ;of;:th'e' repr'oQ;

The adjustability of the mechanism for converting the fore and aft movement of the actuating carriage into a vertical move-- men-t of the work tool supporting arm, may

While the arm has the tendency above I noted, I provide meauspermitting the free vertical and lateral movement ofthe arm, but normally engaging same and moving it away from the work plate, so that while this arm has a'norni-alte'ndency to move so as to engage'the work point with the plate, it may nevertheless b'erso restrained as to be noriiia'lly so held as to maintain the work poimgout of engagement with the plate. I also provide means whereby the work point "may be moved longitudinally of its supporting arm to secure line spacing in the reproduction, or a desired positioning or [placing of the reproduction upon the plate. This latter, however, may also be secured fbyadj'ustments upon the easel-like work fis fppbr F i Inm'achines'df the general type to which my invention relates, it .i'sposs'iblefto use a patternfwhich may be set up thesame as ori tlin ry type, orto use'aipla'te having all of the letters and the di gitsthereon, and bring [the ir'e'd'lettersorfdigits successively into f'th'es'ameposition'with.relation to the patternsufpport,fthe spacing of the 'letters on claims hereto appended.

The. pairs balls 3'4, 35 and 36 positioned between the of cups 31, 32 and 33 are trian'gularly arranged. so as to afiord the desired divergent c supporting points for the carriage 30. The general construction and manner ofsup porting the-carriage 30 is old and well known in this art, and is not essential to the invention, since other well known supporting means for permitting the desired universal 'movement'= may* be substituted thereforfl I i V "Movement isimparted to the carriage 30 by .a tr a'nsmitter arm .37, one end of which is connected 'to said carrlage by means of 1a universal'joint of "any desired type, in a l manner" well" known "1nth1s art,-;-an"d the other end'of which is adapted'tobe oscilupon the pattern plate 28 through :the" medium of a stylus whichvis operativelyconnected to said transmitter arm in a'mannerc which; will be more fully referred tohere- The transmitter' arm is pivotally-su'pported tojhave'universal movement by a a sleeve 38' adj ustablyY mounted upon the column'21, a 'fork39 carriedby'said sleeve, a

Carried by the columns 22 and :23 is a bed plate having laterally extending ways said support and is adapted to serve as a rest for the work plate 6i. The support 59 has set in th'e'upper part thereof, a bar 62 having a sequence of spaced openings as shown, adapted to receive a pin 63 inen gaging relation with the upper edge of the plate 61' so as to hold this plate firmly-in position against the straight edge of the T-square 60. Said straight edge is provided with a set screw engaging one edge of the support 59 so as to firmly clamp the T- square in position" upon said support and permit adjustment thereof toward and from Rotatably mounted with relation to the bed plate 56 is a lead screw 64 having an actuating handle 65, which lead screw engages with co-operating screw threads upon the carriage 5.8 so as to permit this carriage to be moved laterally of the machine in either direction to secure the desired spacing of different characters in the reproduction, or of the whole design upon a plate, as a result of the movement of the work support. This spacing mechanism need be used for spacing characters however, only when long lines are to be etched upon the work plate 61, with individual patterns, or when a pattern plate is used containing all of the letters and digits, which pattern plate in its entirety is shifted and centered relation to the work plate as succeeding letters or other charac- 1615 are to be produced.

Carried by the lead screw164: is a gauge wheel 66 having spaced notches about its edge i pe at n it a t et p to assist in securing accuracy in the spacing movement of the carriage 58. V

.(jarried by the column 2]. 's alaterally extending track 68 having an upwardly prese ited raceway for hearing balls'69, said track 68' forming a means for permitting lineal lateral movement of the. mo l p port for the worli point carrying arm for causing horizontal lines to be described on ment thereof for causing vertical lines to be described on said plate,

Said movablesupport comprises a frame 70 carrying a laterally extending track 71 parallel with and above the track 68 and.

having a downwardly presented raceway,

the-rein adapted to engage the bearing balls 69. The frame 70- in-the accompanying drawings is shown as being connected to the track 71 by means of the clamp plates 72 and clamp screws which, however, is a mere detail of construct-ion to facilitate the positioning of the frame 70' to secure ac-, curacy in the relation of the work point car-v rying arm to the support 59.. Achacent the forward end of the frame '70., or the end 011:

posite to its point of connectionwith' the track 71, is a bearing wheel 74 adapted t0. ride upon an actuating member 75 carried b; I and movable with, the carriage 3.0. The wheel 7 flanges 0 which straddle the actuating member 75. JThe member 75 must be arranged at an incline to impart vertical oscillatory mevement to the frame 70. to cause vertical lines to be described upon the work plate 61, and lateral movement of the frame 70 will result from the lateral thrust upon the Wheel 74 through the member 75. The vertical oscillato' sults from the movement of the member 715 tangentially of the wheel 74. v While I have described the constructio by which the engaging'relation for imparting lateral thrust to the frame 70 through the medium of the member 75, as being a flanged wheel 74 straddling said member 75, it is apparent that any other desired constrmtion for securing this result may be used, although the co-operating tongue and groove arrangement resulting' from the use of the flanged wheel and narrow plate Of the member 75, has the advantage that the cooperating parts may be so closely fitted as to avoid any material lost motion at this point which might develop error in the reproduction.

of certain adjustments to vary the character is a double flanged wheel, the

movement of the frame 70 rev-1 of the reproduction, which adjustments will 7 be more particularly referred to hereinafter. The forward end of the frame 7 0. isprovided wltha fork 76between the arms of which is pivoted a frame 7'? carrying a ver tically depending rigid work point carrying arm 78, having suliici'entlength to permit the work tool or point to behrought into operative engagement with any part of a work plate upon substantially anyportion of the support 59.. i I

To permit :the reproductionto'be placed upon any portion of the plate 61, and also to facilitate the spacing of the line s'of thereproduction, mount upon the arm v78, a sleeve 79 capable of adpistmentlongitudinally of the arm 78, or vertically in relation to the support 59. To facilitate accuracy in the adjustment of the sleeve '17 9 I provide 'gaged-sby a spring pawl86=upon the sleeve the arm 78 with a sequence, of spaced notches or depressions" indicated at'p80, and provide the sleeve-7 9 with a .ratchet'tongue 81"adapted to enter any of said notches; andhold the sleeve in any adjusted position.- The verti- .a -ni96 connected with a link 97, said link cal movement of the sleeve is effected. by means ota rack SQIcarried-bythe arm 78, a pinion 83 meshing therewith and carriedby an extension of the sleeve J79, and an actuating wheelS-l carriedby the shaftxof said pinion. The shaft. of the. pinion 83also carries a ratchet wheel 85 adapted to be en 79,,which pawl and ratchet mechanism-will .co-operatefj'withtherpawl 81 in preventing V accidentalmovement of thesleeve 79- with relation to; the arm 78-. Extending laterally 0f the machine, and 'proj acting to a'sufiicient extent from, the sleeve 79 to secure the ;de'- w sired clear field of vision about same, is a.

holder or mount 87 for a work tool or point v 88,- said work point being adjustablewith relation to said holder, or mount, by means got azset screw 89. .7 s

, The work point carrying arm, 78 is capable v of toscillatory movement toward and from thesnpport 59 aboutcthe pivots76,it being ipiieferable to, provide means as a coiled spring 9OY-acting upon said arm adjacent its point of pivotal support to exert a normal tendency to mo've the arm toward said support. Oneendofthe spring 90is connected z to, an adjustingscrew91 passing through an I ,openingin theupper partof the arm 7 8 and acted} upon by .anfadj usting nut 92 so that the degreeot pressure of the point against the platemay be regulated to that required 60, member 94: carried by afshaft pivoted in suitable bearings upon the support 29. This,

. to remove theresist ,from'thesurface of the -plate, 61 'withouti likelihoodj of the work Y [point 88- penetrating the metal-ofthe plate. VA plurality of openings, one of which is shown -atj93 passing through thefarm 7 8, may be used so that the. efiect ofthe spring maybe controlled either by avariance in'its tension or by "a variance of the leverage at 'which it acts uponsaid arm. The otherend ;of the spring is connected to an armicarried ,b'y the' frame 'FO.

I As. a matter of convenience, it is preferable to have'the arm move automaticallytoward the support 59 and in factbetter work;

results from this practice, since the pressure at the pointwill always be uniform, while if-the arm is forced toward the support-59, there may be a varying pressure with greater likelihood of scratching of thesurface of the ,plate. v The normal'tendencyof the arm 78 to strained by a laterallyielongated bearing member 94l is of suiiicient length to engage the arm 78 at anypoint withinits range of lateral movementso asto permit thedisena -Witl1- machines ofthis general type that The sha-ft95 is provided with a crank being wPiVQl'ECll to s an; oscillatory. link 98.: To raise and lower said: link 98, I employ theor dinarylcrankshaft, link and pedalm'echa} V'nism 99,1 this' ,n1eclianism being shown more particularlyn F 1g, 5 ofthe. drawings.

is a tendency of; the carriage" 30, or similar chine-.1 To correct this condition, I preferwardly in anarc into engaging relation with I zthe arm 78 so asto forceit away from the Y workplatesupport 59, the upward movecarriages, to'zhave a slight jskewing'faction, particularly whentheb'alland cup universal ,support isemployed, which is objectionable when high grade work' is tofbe done on a'ma} beingconnected by, a universal joint-102 with the carriage 30,'and the other end there of being connected by a universal joint with 7' a yoke 103 mounted tohave movement about a; vertical axisin afframe 104 carried uponrear edge of the, table. 20. This expei dien t, however, may be" dispensed with,v if

desired,. altl1ough I preferto use same to preskewing action, When, however, the reducj tion of scale is considerable, this distortion is i not apparent, except to a skilled workman. I Another difficulty I ?have found 7 when operatingmachine's, is. the tendency of the machine to slightly overrun during the fore and aft. oscillation of the transmitter arm 37,-.51.. To correct this condition, Iprovide went/the slight distortion resulting ,fr om friction mei'nbers 10 5 acting upon the side 7 bars as of the carriage actuating'the trans-- 'mitter arm; While such friction members are highly desirable insecuring the best operative effects in the machinait is ,ap-

7 parent that they. may be dispensed with move toward the support 59 maybe rewithout materially affecting the operations "of: other mechanisms inthe-machine, parsame positionas upon "said plate; and the at which the transmitter arm'acts; or modify latter adjustment being for the purpose of permitting the setting of the machine so that during vertical movements of the framev horizontal component will be imparted "thereto sons to cause obliquity in the vertical lines of the reproduced characters. It is possible to'pit'ch the letters in either direction 'according'to the manner of adjustment of themember 75. i 7

By adjusting the member 75 about its horizontal axis, I am also enabled to cause the actuation of the frame 70 and the parts earned thereby, to maintain the exact scale,

infthereproduction of t-he'characters, as defined by 't l'ie adjustment of the leverage the, scale of the reproduction as to the vertical lines only by either increasing or de" creasing theverticalmovements of the frame 70 independently of the leverage of the transmitter iann, thus either extending or condensing the reproduced characters.

I In'tlife embodiment of the invention shown in the drawings, the above adjustments are "secured by" providing the carriage 30 with an upwardlyextending bearing stud 106 upon which. sleeve 107 is rotatably mounted and capable of being set in any-adjusted position by'me'ans ofa set screw 108. The sleeve 107 has an extension 109 through which passes a bearing pin 110 upon which the. member 75 isloosely mounted. This pin is fixed in relation to the sleeve 107, and has an index finger 111 secured thereto. 7 The other end ofthe bearing pin 110 is screwthreaded and adapted to receive a clamp nut 112' The'si'de or the member 75 adjacent the index'finger 111 is provided with suitable graduations for thejpurpose of permitting accuracy in the setting of this plate.

When the member 75 is adjusted about its verticalaxis, it is desirableto turn the flanged wheel 7 4 about] a vertical axis to "avoid unnecessary frictional. this polnt, and

avoid likelihood of the said wheel passing 'ir'om the traction surface of said member. To pei'init this adjustment of said wheel, I journal its shaft in a forked swivel 113, mounted in a vertical bearing 114 and havengaged by a clamp nut 116. 'By loosening the clamp not 116, the wheel 74 is permitted to turn freely about a vertical axis, the

mg a screw-threaded shank adapted to be oliine for introducing obliquity in the oharacter of thereproduction.

Preferably I provide the frame with an extension 117 having adjustably mounted thereon a weight 118 which will have the effect of counterbalancing said frame and the arm 78 carried thereby to an extent to ensure thedesired ease in the operation of the machine, and reduce the variance in the resistanc'eito the'operation of the tracing stylus 55 when imparting vertical movement to the frame 70through the member 75, particularly an upward "movement of said frame.

' The operation of the herein described mechanism is substantially as follows In describing the ope'r-atmn of the machine, it will be assumed that the various parts are in the position shown in Fig. 1

or the drawings, and that a pattern platebearing both upper and lower case letters 7 and digits, is to be used upon the machine.

by the support 59"wil 1 read from the same Whon a machine is setas shown, the posiposition as the corresponding matter upon the plate 28', but will be severally. reversed and i-n the aggregateread fromrig'ht to i leithinsteadoi from left to right. In other words, the configuration of the seve'ral letters or characters will, in the reproduction,

beqthe reverse of the same letters or characters upon the pattern plate 28, and theirposition in relation to each other will also be reversed, as requireclin printing.

The position of the actuating plate 75 corresa'ondin-g with the showing of Fig. '1, is shown inor-e clearly in Fig. 11, ofthe drawingsyand in Fig. 16 the lower line oi letters 1ndicates the relation an-d formation of the letters upon the pattern plate 28, while the upper line represents the reproduction of these upon thoplate 61. The angle to the horizontal at which the actuating plate 75 is set must be governed byfthe ratio of the portions of the transmitter arm 3751'up'on opposite sides of the pivots 413 in orderto preserve the proportions between the *vertical andhorizonta'lplane oi the reproduction as compared with those of the characters upon the pattern plate.

When. a machine has been properly set, a plate 28 is positioned with the first letter in a definite position upon the pattern table 524: and the stylus 55 is passed along the depressed lines of this cha r-acter' with a iesultant oscillatory movement of the transinitter arm 3751 by the'sty lus ar m ii -and transmitter arm. Since 'the'transmitter arm 37 is pivoted intcrmediate its ends, move-e ments of the stylus 55 to theright or left causes a movement of the carriage and the" actuating plate 75'carried thereby, tothe left or right of the machine; and movement of the stylus forwardly orv rearwardly .of the pattern will cause a rearward or forward movement of the carriage 30. The plate 75 being inclined forwardly of the machine, itis apparent that. its rearward movement Will permit the frame 70 to descend, carryifthe arm 78 outwardly of thesupport ;59 r 60 ing with it the work pointsupporting arm 78, and since the letters upon the pattern read properly, and not reversed as required imprinting, the top of the'letters will appear toward the top of the plate'6l, since'the 7 normal tendency ofthe, transmitter arm -3751 to reverse the direction of movement of the work pointis counteracted by the" position of the plate This plate 7 5, however, does not. in anyway modify; the

operative effect of the transmitter arm-asto V lateral movement of the frame '70 and arm '78 for describing' horizontal lines. It will be' understood that the universal mount for the carriage '30, and the tracks 68-471, ea

mitting :lateral and Ivertical movement of the arm :78 will introduce a lateral component of movement to the arm,78 during its verticalmovement, where required,so as. to permit the reproduction of lines ofrany configuration upon the plate '61. r

,callyyof said support, andthatthe substaritiallygvertical position of theface'of, said support, or its right angulararrangement. 'withrelation to thepattern table 24, permits 1 f the operator to simultaneously watch both ;Fromthe foregoingit will be seen that "the essentialcharacteristic of the present invention, or the no rmal functioning of the machine, is the employment of a-ipatte rn supporting table and a work support arranged at substantially right angles to each otherand so spaced as: to permit the opera-V s :tor to at the time, observe both the tracing" stylus" and the reproducingwvork point,- a construction necessarily, involving a pantograp'hic reproducing mechanism. in

the fore an d'a-ft lines the pattern, or the of the work point. It is to'be understood that where I havereferred tovertical move- 7 -ments, I have included therein the vertical with the workiplate' 61. When, 'howevmxl it is desired to e'ngage'thepoint 88 with said oomponentpf movementwvher-e there is -simultaneous v'ertlcal and lateral .movement of oblique or curved lines, 3

which 7 the movements corresponding with I rearwardly, whether the letters or other pla-nation.

Again these adjustments may be used when it is desired to impart a tilt, or obliquity to the letters or other characters, either forwardly or characters are reproduced to scale or extended or condensed .as above referred to. If 1t be des red to vary the length of the lateral or horiZontal'lin-es in the reproduction, this maybe done by the usual adjustment elf-the ring 10, the operative effect of whichadjustment is well known in this .art, and-therefore requires no detailed eX- the vertical lines of the reproduction may be secured by the adjustment of the actu- To secure this adjustjamb nut 1'12 and rotate the member 75 about its pivotal support 110 so as to increase or decrease its angle of inclination.

' If the angle of inclination be increased, the

result will be an increase in the length of the vertical lines of the reproduction. If the angle be decreased, or made more acute. the result will be adecreasein the'length of such lines. This condition prevails-irrespective of whether the setting of th member 75 issuch as to reproduce the letters or other characters so that they will read in thesame'd rection as-mthe pattern, and as shown in Fig. 1- of the drawings,

or whether it "be given the reverse pitch or inclined toward the rear of the machine so as to' reverse the-letters upon the reproduction, or place them upside down.-

Fig. 10 illustrates the adjustment of the member 75 when the letters are to bereversed, and Fig. 11 shows the adjustment when the angle of inclination of the member 75 is the same as shown in Fig. 1 of the drawings, except as tothe pitch of the The cathe degree of inclination of the member "75 results from the fact that the lifting action of said member, with the same quantity of movement fore and aft of the ma chine, will vary with any change in the pitch of inclination; the higher the pitch,

the greater the quantity of vertical movement. and the lower the pitch, the lesser the quantity of such movement. It is to be noted that if the member 75 be set as shown "tiv-ely.

The variance in the length of.

in Fig. -9so :thatits upper surface engaging the wheel 74L is up'onra horizontal plane, there will be no vertical movement of the work point .88, this point being held in the lateral movement imparted therethrou-gh to r the work point.

lV-hen an desired to impart obliquity to the lines in the reproduction cores'ponding with the vertical lines .on thepattern, .or the lines having a vertical pitch, it is merely necessary :to release the set screw 108, swivel the sleeve 107 about the vertical axis of the stud 1 06 eitherto the left or to the right, as shown in Figs. 13 and 14 respec- It the vertical and lateral pitch of the member 75 be as shown in Figs. 11 and 13, the letters in the. reproduction will be pitched to the right, and the .eii'ect would be the same it the vertical and lateral pitch of the member 75 be the same asshown in pit-ch. -Assum'in'g that themember 75 is set as shown in Figs. 11 and 1d, the reproductionw-ill have a pitch to the left, while it the setting be as shown in Figs. 10 and 14 the pitch would be thejsame torthe reasons stated above in connection with the setting in accordance with Figs. 10 and 18.

Since the degree of inclination of the member 75, fore and attof the'machine, does 1130i) in any way afiect the lateral component of motion introduced into the ver tical lines as a result of the inclination laterally of the machine as shown in Figs. 13 and '14:, it is apparent that the adjustment shown-in Figs. 13 and 14: may be used irrespective of-t'he' scale of reproduotiomor whether this scale is an exact scale or is modified 'to condense-or extend the vertical dimensions ott'he reproduction.

It is apparent that the degree of tilt or inclination of the reproduced letters maybe varied "by changing the degree of lateral angularity or inclination of the member 75 from that shown in Figs. 13 and 14.

It is to be understood that the scale of the reproduction may be secured, Orvarie'd, by adjusting the sleeve 38 vertically of the column 21 in the usual and well known manner, upward adjustment reducing the scale, and downward adjustment increasing the scale. I

The vfunctioning of the rod 101Yis merely the spacing for the-purpose'of correcting any tendency ofthe carriageBO to have a twisting action as it receives universal movementthrough the transmitter arm; 3751, paiflticularly' during lateral movements of the carriage. For securing line spacingupon a plate, the knurled handheld 84 is used to simultane' ously actuate the pinion 83 and the ratchet wheel'85 to impart movement to the sleeve 79 longitudinally of the work'point supporting arm 78. While' the ratchet wheel and pawl 86 will ordinarily serve to hold the sleeve 79 and the mount 87- carried thereby in any adjusted position, I prefer to use the tongue 81 co-operatingwith the notches or recesses SO in the. arm 78E015 supplementing, the action of said "pawl and ratchet mechanism.

c Itwill be readily understood that letters or characters of the reproduction are readable I from the'same positionv as those upon the pattern; that movement of the sleeve 79v willof necessity be downwardly in setting the machine for the makingi of succeeding lines, while if the. letters or characters of the reproduction be reversed,

movement of the sleeve 79 wlll necessarily "be upward."

. The manner of connecting the stylus arm.

54with the telescoping extension 51 of the transmitter; arm: 37, is such as to minimize lost motion in this connection, b ut' the construction employed is not essential to the invention; When the-construction used, however,' fore and aft movement of the stylus arm will cause the side andcross bars 7 46-47 and the carriage 49' to move longitudinally "of the machine'lupon the bearlng' balls 45. Lateral inovements of said stylus arm will impartl'movement to the carnage 49 laterally of the'macliine, the bars 46 -47 lines reproduced in the reproduction.v V

j Theretard members serve merely'zto having no movement therewith. v course5 it will be readily understood that when the vertical moYement' has a lateral component,

or Vice versa; there will be simultaneous movement ofthe bars 46%47 fore and aft of I the machine and of the car'riagefl49 laterally of the machine, the relative movement of the parts definingthe character ofthe check a tendency of the bars 46947 and the carriage49 to overrun jdurin'gtheir rearward movementwhen they are largely re- V l ieved from theload of the'frame70 because the member 7 5eis pitchedvas shown in' Figs;
